I fell onto a toy 3 weeks ago and perforated my eardrum. It started to bleed so I went to the ER and was given neomycin/Polymyxin B otic suspension drops. I used them one time (3 drops) and then read they shouldn't be used with a perforation so I stopped. A day later my ears started ringing, this also coincided with the day the blood dried.
Is it normal to have high-pitched ringing from a perforation or from a scab/dried blood on the eardrum? Or should I be worried that the eardrops have caused damage to my inner ear? I saw an ENT who said not to worry about the drops but it is so hard not to after the terrifying things I've read. He confirmed dried blood on my eardrum. Hearing test was good.
If ringing is from the perforation or the scab, how long should it take to improve? Ringing is no matter after 3 weeks.
Also, since my ear was bleeding when I used the drops, is there risk of toxicity from the neomycin entering my bloodstream?
